memoir.

To aZZ whom it may concern:

Be it known that I, JAMES W. Hnnnr, a citizen of the United States, residing at Gooding, in the county of Gooding and State of Idaho, have invented certain new and useful Improvements in Hydrocarbon- Engines, of which the following is u specification.

This invention relates to improvements in hydro-carbon engines and more particue lerly to a multiple stroke engine adapted to complete the four strokes of each piston ulpog3 each single revolution of the power s ai One or the principal objects of the inven-,

ticn" is to provide a cam shaft in place or the ordinary crank shaft; the cam shaft being disposed to be rotated by the pistons in a manner that will cause the cam shaft to revolve once upon two complete recipro cations of the pistons.

A further object of the invention is to provide a four cycle hydrocarbon engine aving e. plurality of driving pistons op" erating in cylinders adapted to receive an explosive charge at predetermined intervals governed by a direct connection of the valves with the cam shaft thus eliminating the use of timing gears now generally employed on engines of this character.

The invention further aims to provide an engine of this character that will be constructed to cause strokes of the piston to be multiplied two-fold with respect to the revolutions of the, power shaft,wherebya greater speed of the pistons may he maintained thereby permitting the use of a comparatively small quantity of explosive mixture ejected into the cylinder upon each power stroke of the piston.

A fiirther object of the invention is to provide an engine of this character that will be more eilicient in operation and less complicated and lighter in construction than the enginespow generally used.

further object of this invention is the provision of a device of this character which is siinple in construction but durable and ,well adapted to withstand the rough usage,

to which devices of this character are ordinarilysubjected.

For a full description of the invention and the advantages and merit thereof. rot.

erence is to he had to the following description and the accompanying drawingswhere Specification. of Letters Patent.

in is illustrated the invention in which Figure 1 is a top plan.

preferred form of my Fig. 2 is a vertical section taken on the]' line 2-2 of Fi 1.

Fig. 3 is a section taken on the line of F19 2.

Referring to the drawings wherein is illustrated the preferred form of my inven-, tion, in which like numerals of reference indicate correspondingparts throughout the several views, the engine casin -1 has the driving shaft 2 extended theret rough and this shaft may he of any desired length according to the number of cylinders employed in constructing the engine. Mounted upon the top of the casing are thelaterally spaced apart cylinders 3 and 4: which are.

disposed vertically and have their interiors in communication with the interior of the can'ng 1. These cylinders are spaced at equal distances from the center line of the casing and are each provided with a piston 5 connected to a connecting rod 6 extending p 30 mounted within the casing, on A lugs 7 carried by the top wall". of the casing, is a rocker beam 8 which, in. instance, is'constructed of frame downwardly into the casing 1.

?ivotelly the ears or the present bars 9 connected at their proximate ends and pivoted, on the pin 10, to the lugs The outer ends of the frame bars 9 are bifurcated and the tenninals gof the bifursated ends are integrally connected to the brace bars 11 which are laterally spaced apart and maintainthe arms 9 in proper posit on and prevent collapsing of the beam when the same is in operation. The ends;

of the bifurcated portions of the arms 9 are:

apertured to receive pivot plnsor journals 12 each of which carries a roller or wheel 13. The lower ends of the piston red are also bifurcated asshown in Fig: 3 of the drawing and these bifurcated ends extend around the rollers and are I pivotahly connectcd to-the journals 12. i 1

Mounted upon the shaft 2 is a cam 14 which. as shown to advantage in Fig; 2 of the drawing, is an elongated plate having each end rounded and its longitudinal marginel edges straight thus forming a cam surface against which the peripheries of the rollers 13 are'engaged.

The rocker beam is so mounted as to cause the rollers 13 to contact with the cam surface Ill at all times as shown by full and dotted lines in Fig. 2.

Mounted upon the shaft 2 is a valve cam l5 engaged by the rollers 16 carried by the. ends of the valve ,rods 17 which extend to the top of the c)-'linders and are connected to rocker arms 18 pivotally mounted and which are joined to the valve stems 19 of the valves 20. These valves are adapted to open and close the ports cylinders for permitting the intake ofan explosive charge and the exhaust of the gases after the explosion occurs.

In operation, the explosive charge will be supplied to the cylinders in any preferred manner and assuming the structure to min the position shown in full lines in Fig. 2, the explosion occurring in the cylinder 4 will force'thc piston downwardly and the downward pressure will be exerted by the roller 13 on the surface of the earn and cause the same to rotate in the direction mchcated by the arrow in Fig. 2. The frame or rocking beam being pivoted will cause the roller to swing inwardly toward the center of the shaft and thus impart rotary movement to the cam which. being fixed to the shaft, will cause the shaft to rotate. Thisdownward movement of the piston in the cylinder 4:

will cause an upward movemcntof the piston in the cylinder 3, this being the exhaust stroke of the piston. By virtue of the continual contact of the rollers 13 with the cam,

; however, each piston will have made a complete reciprocation within its cylinder when,

the cam has moved'around to the vertical position shown dotted lines in Fig: 2, the shaft 2 having made only a half a revolution. Therefore, the piston in the cylinder 4 has received its power and exhaust stroke and the piston in the cylinder 3 has received its exhaust and intake stroke.

The cylinder 3 will then receive its power and compression stroke and the cylinder 4c its intake and compression stroke. In this manner the four strokes are completed in each cylinder upon a single revolution of the cam. And two cylinders will thereby accomplish the work of four cylinders of the ordinary type. employing a crank shaft. The

rollers 16 are always in contact with the cam 1 15 and since the valves '20 are "opened for the purpose of admitting the explosive charges by direct contact with'cam on the shaft 2 it will be seen that timing gears and counter shafts are QllIlllIlEltBClalHl the pistons will operate at a comparatively great speed with respect to the speed of the shaft. wheel may be mounted upon the shaft 2 in the usual manner for the purpose'of properlv' balancing the shaft during the operation of the motor.

It will be also noted that the construction provides novel means for converting the reciprocatory movement of the piston into a in the top of the,

are given an oscillatory movement in add'i tion to their reciprocation whereby the rollers will properly engage the cam surface to impart a rotary motion to the cam which transmits the same to the shaft 2. The oscillatory motion is obtained by virtue of the pivotal mounting of the rocker element which has its ends connected with the rollers and the ends of the piston rods.

From the foregoing it will be observed that a very simple and durable hydro-carbon engine has been provided the detail. oi. which embody the preferred form. I desire it to be understoochjhowever, thatslight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claims hereunto appended.
